The Diet and Preparation Before a Colonoscopy
Do you want to know more about the diet and preparation before a colonoscopy?
A colonoscopy is an exploratory medical exam that you perform with the intention of diagnosing and treating different illnesses that can be present in your colon, more commonly known as the large intestine.
This process is done with a device called a colonoscope. It’s a flexible tube (approximately 150cm long) and 1cm in diameter with a tiny camera on it. This device is inserted in the anus and is carefully slid through the large intestine, allowing it to:
- See its inside, ruling out illnesses.
- Allows the development of a treatment.
- Carry out diagnostic tests.
- Remove intestinal polyps.
- Obtain biopsies
- Remove tumors.
However, to perform this process, your large intestine needs to be free of feces. Therefore, it’s necessary to start preparing your diet and laxatives at least 3 days before.
A Bland Diet and a Colonoscopy
A bland diet is a type of diet used to eliminate problems related to the digestive system and colon cancer, including:
- Surgery in your jaw, mouth, or digestive tract
Generally, when this type of diet is administered for before a colonoscopy, it’s an excellent method of preparation for it. It easily cleans your large intestine in a non-intrusive manner.

- Don’t drink liquids between 3 and 4 hours before the colonoscopy. The only exception is in some moments where you’ll be required to drink water to take medicine prescribed by your doctor.
- Keep your doctor informed about the evolution of your bland diet and whatever illness, allergy, or side effects that could happen from some medications.
- Similarly, it’s important to let them know any operation that you have previously had, above all in the case of prosthesis or disease in your heart’s valves.
- Read and sign the consent form stating that you understand that the procedure is an exploration of your large intestine through a colonoscope.
- Go in accompanied by someone you trust that can be responsible for bringing you home after the test. Keep in mind that the affects from the pain killers and sedatives can last for hours.
After the Colonoscopy
Through a colonoscopy, your doctors will recommend that you continue a bland diet for at least 3 more days to help your body with the expulsion of gases and fecal matter in the following days. This way, your digestive system won’t be affected by the procedure.
